Modified Citrus Pectin (MCP) is a patented, low molecular weight citrus pectin that can pass through the intestinal barrier so it can work systemically. MCP can bind to and facilitate the excretion of low levels of heavy metals from mild, but common environmental exposure. Studies indicate that MCP promotes healthy urinary excretion of heavy metals from typical everyday exposures without altering the retention of other nutritional minerals, including calcium, magnesium, iron, copper and selenium. In addition, MCP has been shown to support healthy cellular growth and reproduction
